Answer:
2
Step-by-step explanation:
let the number be n, then
n = 4n - 6 ( subtract 4n from both sides )
- 3n = - 6 ( divide both sides by - 3 )
n = 2
That is the number is 2
-1. -1 *5 = -5 you just have to divide 5 on both sides which will give you n = -1
Answer:
5
Step-by-step explanation:
o+5=y=5
1+5=y=6
2+5=y=7
.:y=x+5
Answer:
m∠BEF = 65.3°
Step-by-step explanation:
Given:
m∠DEB = 27.2,
m∠DEF = 92.5
Required:
m∠BEF
SOLUTION:
Since B is the interior of ∠DEF, it means ∠DEB and ∠BEF are adjacent angles that make up ∠DEF. And they share the same side, BE.
Therefore:
m∠BEF + m∠DEB = m∠DEF (angle addition postulate)
m∠BEF + 27.2 = 92.5
Subtract 27.2 from each side
m∠BEF + 27.2 - 27.2 = 92.5 - 27.2
m∠BEF = 92.5 - 27.2
m∠BEF = 65.3°
Set up a proportion:
8 gallons 1 gallon
------------------ = -------------------
25.60 dollars x dollars
Then, cross multiply
8x= 25.60
x = 3.20 dollars
